Laser angle guide assembly for computed tomography and method for operating the same

Abstract

A laser angle guide assembly has a stand, a laser guide and a reflector. The laser guide is mounted adjustably on the stand and has a body, a side index line, a front index line and an index protrusion. The side index line is formed on the side faces of the body. The front index line is formed on the front face of the body. The index protrusion is formed on the front surface at the bottom of the body and has an inclined top and a front face. The reflector is attached and inclined relative to the front surface of the laser guide at an angle and has a reflecting side facing to the inclined top of the index protrusion. Accordingly, the laser angle guide assembly can provide a guide effect to help a doctor to puncture a needle assembly at a desired angle precisely.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a laser angle guide assembly, and more particularly to a laser angle guide assembly for computed tomography (CT) and a method for the same.[0003]2. Description of Related Art[0004]Computed tomography is a way to scan a patient for biopsy, and a specimen of tissue will be removed from the patient and be examined by a pathologist to check diseases, such as cancer. A doctor will remove a specimen of tissue from the patient with puncturing a needle assembly in to a patient's body at a desired position, angle and depth determined by the computed tomography. However, there is no guide for the puncturing angle during the specimen process, so a laser angle guide assembly is provided to generate an index line to help a doctor to puncture the needle assembly into the patient's body.[0005]However, during the puncturing process, the laser angle guide assembly has to be removed so that the angle for ...

AI Technical Summary

Benefits of technology

[0007]The main objective of the invention is to provide a laser angle guide assembly that can provide a guide effect to help a doctor to puncture a needle assembly at a desired angle precisely. The laser angle guide assembly has a stand, a laser guide and a reflector. The laser guide is mounted adjustably on the stand and has a body, a side index line, a front index line and an index protrusion. The body has a front face, two side faces, a top and a bottom. The side index line is formed on the side faces of the body. The front index line is formed on the front face of the body. The index protrusion is formed on the front surface at the bottom of the body and has an inclined top and a front face. The reflector is attached and inclined relative to the front surface of the laser guide at an angle and has a reflecting side facing to the inclined top of the index protrusion.

Problems solved by technology

However, there is no guide for the puncturing angle during the specimen process, so a laser angle guide assembly is provided to generate an index line to help a doctor to puncture the needle assembly into the patient's body.

If the puncturing angle has a large deviation relative to the desired puncturing angle, this will cause pain to the patient and even to lead complications to the patient.
